LOCKING DEVICE FOR STEERING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 610,485, datedSeptember 6, 1898. Application filed November 28, 1897. Serial No. 659,616. (No model.)

To all whom, it may concern.-

Be it known that IJVILLIAM E. HAMMOND, a citizen of the United States,residing at Onset Bay, in the county of Plymouth and State ofMassachusetts, have invented a Locking Device for Steering Apparatus forVessels, of which the following is a full, clear, and exactdescription,refereuce being had to the accompanying drawings, makingpart of this specification, in which Figure l is a front elevation of asteering apparatus for vessels having my lockingdevice applied thereto.Fig. 2 is a central vertical section of the same on the line 2 2 ofFig. 1. Fig. 3 is a plan. Fig. 4 is a vertical section on the line 4 4.of Fig. 2.

My invention has for its object to provide the steering apparatus of avessel with a looking device by means of which the wheel can be securedin any desired position, thereby holding the rudder securely in placeand enabling the wheelman to attend to other duties, if necessary.

With this object in view my invention consists in certain novel featureshereinafter described, specifically pointed out in the claim.

In the said drawings, A B represent a pair of standards in suitablebearings, in which is supported the wheel-shaft O, to which is securedthe steering-wheel D, the shaft being of larger diameter between thestandards to form the drum or barrel E, upon which are wound thesteering-ropes b, which are connected with the tiller G of the rudder inthe usual manner.

To the shaft 0 just inside the standard A is immovably fastened atoothed wheel H, having square teeth 10, said wheel being preferablymade, as shown in Fig. 4, in two parts and having its hub f providedwith flanges 12, which are clamped together by means of bolts g. To thestandard A on the side next to the wheel D is pivoted at h a locking-dogI, having at its outer end a bent arm 15, which is adapted when swungdown to engage the teeth of the wheel H, and thus lock the same afterthe steering-wheel D has been turned. to bring the rudder intothe'desired position, thus looking and holding it securely in place andenabling the wheelman to attend to other duties, if necessary.

The top of the standard A is provided with a square notch m for thereception of the bent arm 15 of the locking-dog I, which is thus heldfirmly by the side walls of saidnotch close to the toothed wheel H andthe liability thus avoided of its being bent by any strain to which itmay be subjected.

The above-described locking device may be applied to steering apparatusof all descriptions, either for large or small vessels, and thewheel-shaft may be provided with a barrel or drum for the wheel-ropes,as shown, or with a screw-thread or other suitable means fortransmitting its motion to the rudder. The locking-dog may be pivoted toone of the shaft-supporting standards, as shown, or to any othersuitable surface adjacent to the toothed wheel H.

What I claim as my invention, and desire to secure by Letters Patent, is

In a steering apparatus for vessels, the combination of thesteering-wheel shaft having a toothed wheel H immovably secured thereto,the supporting-standards A, B, the former provided at its top with asquare notch 'm in close proximity with said toothed wheel H, and thelocking-dog I, adapted when in engagement with said toothed wheel to liewithin the notch m in the standard A, all operating substantially asdescribed.

Witness my hand this 16th day of Novemher, A. D. 1897.

WILLIAM E. HAMMOND.
